원격 교사 연수는 기존의 교사 연수를 보완할 수 있는 장점 때문에 그동안 많은 양적인 증대가 있었다. 그러나 이제 양적인 증대와 아울러 그 질적인 면도 같이 고려해야 할 때이다. 기존의 원격연수는 시간과 공간의 제약성과 연수생의 개별학습을 고려한다는 장정이 있지만 연수 강사와 연수생간의 상호작용의 문제점, 연수생의 요구에 부합하지 못하고 현장 적용성이 떨어지는 연수내용, 명확하지 못하고 획일적인 평가방법, 연수강사의 질, 교수 학습 모형 등과 같은 문제점들이 제기 되고 있다. 특히 원격 교사 연수의 핵심인 교수법을 향상시키기 위해서는 실제적이고 객관적인 평가 방법이 필요할 것이다. 따라서 본 연구에서는 교사의 언어적, 비언어적 행위에 대한 분석을 기반으로 하는 웹기반 평가의 프로토타입을 개발하여 교수법을 향상시키고자 한다.

Recently, web based virtual trainings in the teacher training are on the increase. However, we have evaluated only about hardware systems of virtual training systems and considered a question in their good aspects. Now, it is time we evaluate the problems of virtual training systems and search the solutions of them. However, we have no chance to evaluate of problems of each virtual training systems. Therefore, we will analysis management aspects some web based virtual training courses and propose the solutions of them.

Web-based distance teacher training should focus on increasing self-directed problem solving skills of trainers by problem-based instruction(PBL). Performance assessment evaluates achievement of learning goals through the practical performance learning to solve problems in the real situation. This study proposes a web-based performance assessment model for the distance teacher training. It reflects fairness and objectiveness issues of performance assessment which elementary teachers are concerned about through the survey on distance teacher training, and relieves instructors from overload of managing and scoring performance tests. The proposed model provides problem-based learning situations, interactions between individuals and groups, and web-based cooperative evaluation and the peer evaluation.

This study aims towards developing design guidelines for teachers' professional development programs (PDP) that help to improve self-regulated learning skills through OER (Open Educational Resources). To achieve the research objective, first, literature review and case studies about famous OER collections were conducted, and from these reviews, twenty-six guidelines according to ten categories suggested by Zimmerman & Martinez-Pons were derived and finalized into fifteen items in nine categories through review of five experts. Based on the guidelines, a prototype of a teacher's PDP was implemented and evaluated by seven teachers. Results of the usability evaluation proved that the design strategies implemented in the prototype might contribute to improving teacher's self-regulated learning skills and helped to find the teacher's needs based on their PDP.

The purpose of this study was to provide guidelines for the effective operation of Web-Based Training (WBT) for early childhood teachers. Based on content analysis and questionnaires administered to the 174 current trainees, this research analyzed (1) the educational effectiveness and learner satisfaction, (2) the operation and management, and (3) the system, interface, interaction and communication, motivation and content design of $WBT^{***}$. Results showed that most trainees were very satisfied with the WBT because the program provided plentiful professional information enabling them to pursue their educational objectives along with flexibility of time and space. On the other hand, system stability, communication, motivation, and content design need to be improved. Based on the research results, 8 strategies of effective management of web-based early childhood teacher training were proposed.

Even though the distance education via Web has a great advantage to overcome time and space, its problem that the management of trainees is not efficient compared with classroom and group education. This problem is a great obstacle to the objects and achievement standards of distance education, giving controversial arguments to the advocators of distance education. Distance educators need to monitor the trainees 'participation and responses continuously and offer appropriate feedback to the trainees. However, the existing distance education system only focuses on teaching and teaming activities, and as a result, the efficient management function of distance education is not available. Accordingly, the study attempts to find out the appropriate managing elements of distance teacher training in order to effectively achieve the goals of teacher training and the efficient management of distance education. Also, it proposes distance teacher training system that offers appropriate feedback to trainees, applying the derived elements of distance teacher training to the training processes. To verify the efficiency of the system, hypotheses on related items of distance teacher education and learning types are suggested, and the achievement of learning and its relations are investigated through questionnaire of learning types.

In this paper, a cyber training institute system suitable for teachers' training is designed and implemented, and it is applied to and evaluated on the actual spot. While general purpose cyber education systems have too much unnecessary functions and are inconvenient to operate, this system removes the unnecessary functions and has only useful functions. This system is much concerned with the interaction among learners, instructors, administrators and contents. This system is characterized by having menu items such as Searching Learners, Taking Attendance, Information for Learners, Assignment Hand out, Group Debate, Cyber Cafe and Access Statistic to promote the interaction. The result of the application of this system to 554 teachers for two years is that the ratio of completion was 95%.

최근 본인에게 어울리는 색상을 배경으로 촬영하는 감성 증명사진이 유행하고 있다. 개인마다 퍼스널 컬러를 찾아 배경색에 적용하는 것은 시간, 비용, 인력적으로 어려움이 있으므로 자동으로 개인에 따른 배경색을 찾아서 사진을 합성하여 감성 증명사진을 제작해 주는 딥러닝 기반 시스템을 구축하였다. 본 논문에서는 Convolution Neural Network 를 기반으로 한 딥러닝 기술을 이용해 Image Matting 과 Multi-Label Classification 을 수행하여 기존 감성 증명사진들을 학습하여 모델을 구축하였으며, 해당 시스템으로 사용자에게 새로운 배경색이 적용된 감성 증명사진을 제공하는 웹 애플리케이션을 제안한다.

Web-based teaching-learning systems through the internet has continuously pursued the learner-centered educational environment by promoting the interaction between leachers and students. As a result, learners haute become free of the limit of time and space and have more ways to have access to education information more easily. Consequently, the development of the internet has resulted in the changes of the educational environment. Web-based distance education through the internet is now expected to be applied widely in various fields of education. In fact, distance education through the internet has taken place in a new education paradigm. The purpose of this paper is to promote the economical and educational efficiency of all the procedures from developing the system to operating in a remote training cyber system. Therefore in developing the system, we designed it to raise the efficiency by making main modulo into components and by reducing the terms and cost by reuse. Also lute meant to raise the efficiency of education by applying constructivism as an educational basic.
